Last week I put a FET + 7135 Driver - 15mm - MTN-15DDm , with Crescendo firmware, in my On The Road i3!
It improved the usability of the flashlight and also the luminous levels.
Maybe not the “throwiest” light in the category but for a 16340 flashlight with XPL-HI U6-1A, it reaches more than 200m in throw 
House @185m .
Some more photos here.
